ニットシャツの着衣バストシルエットに及ぼすブラジャーの影響

抄録

Bust silhouette is one of several very important aesthetic points in the appeal of a women’s body, and it is also well known that an attractive silhouette is influenced by both inner and outer garments. Some odd protrusions can appear in outerwear because of the underlying brassiere, in particular, in spring-into-autumn apparel. As a result, many young Japanese women experience discomfort related to this silhouette. Thus we investigated the relationship between the brassiere and the bust silhouette in knit shirt. The experimental results are as follows: (1) unnatural protrusions result from four causes: the seam, the cup line, the trim lace, and the malformed top part of the brassiere, (2) seamless cup type brassiere makes a contribution to a beautiful bust silhouette, and (3) characteristics of the half-cup type brassiere which produces the worst bust silhouette in knit shirt are the total angle of cup top (B_θU + B_θL) ≤ 155°, the curved height of the under-cup line (B_BL) ≤ 6 mm, and the compression recovery (RC) ≤ 50%.
